Choosing The Right High Purity Di Resin For Your Needs: Therefore As Water Passes Through The Resin Beads

deionizationAnother question is. Can the kind of high purity DI resin really make a difference in the quality of your product? Absolutely. Consequently, this process is known as Ion Exchange or Deionization. As water passes through the resin beads, all the other positively charged ions, similar to magnesium or iron, stick to the cation resin and dislodge the lightly charged hydrogen ions. Which process you choose depends on your specific water application needs. Let me tell you something. The more you know about the different kinds of DI resin that are available, the easier it gonna be to choose the right type for your application. Hydrogen ions are very lightly charged ions in water. Normally, there’re three deionization kinds processes, every requiring another composition of resin. On top of that, we’ll explain how DI resin works before discussing how it interacts with the three deionization types processes.

In a similar exchange process as the cation resin, water runs through the anion beads, that attract the negative ions like chloride and sulfates. Which one you choose depends on your water application requirements. You see, this water combines with the now decationized water to form hydrogen hydroxide or pure H20. You should take this seriously. There are three different kinds of deionization, all of which are determined by the resin type used in the process. We use two cation types resin. It is strong acid and weak acid.

Weak base deionization -This process uses a strong acid cation and a weak base anion to create the lowest quality of deionized water.


Whenever giving the water a low pH, The weak base anion allows CO2 and silica to flow through. Strong base deionization -This process uses a strong acid cation and a strong base anion to create ‘midrange’ quality deionized water. This upgraded sort of deionization removes all the CO2 and silica from the water.

Mixed bed deionization creates water with a resistivity amount of more than sixteen megohms. High purity mixed bed water can only be measured with a resistivity meter, preferably a temperature compensated resistivity meter. The other consideration regarding deionized water is your necessary capacity of treatment. Conductivity meters are not sensitive enough to measure high purity mixed bed water. Deionization canisters can purify anywhere from a quarter gallon of water per minute all the way up to 500 gallons per minute.

So in case your application requires a lot of deionized water, it might be wise to consider a reverse osmosis unit.

Click on the form below, Therefore in case you have any questions about the deionization process and selecting the right resin for your needs. For example, resin is the life force behind the deionization process. Whenever taking a bulk of the work off the deionization canisters, a RO unit can remove a large percentage of the charged ions. Our engineering department may be happy to assist you! Choosing the right resin type depends on your specific water treatment application or need.
